Specification of Letters Patent.

Application filedNovember 1,1916. Serial No. 128,947.

To all whom it mag concern:

Be it known that I, VVHnn nR E. Smrrma citizen ofthe United States, residing at Pueblo, in the countyof' Pueblo and State of Colorado, have inyented certain new and useful Improvements in Window-Sashes, of which the following is a specification, reference being had therein to the accompanying drawing.

The object of the invention. is to provide a sash which is so constructed that the mullions will be connected together and secured within the stiles and: rails of the sash in such a manner that the costof manufacturing a sash will be greatly reduced.

Another object of my invention is to provide a sash construction in which the ordinary mortise and tenon joint is. eliminated for securing the mullions together, and a joint is provided which can be cheaply; formed, and one. in which. the weakest part of them-ullion is. cut to receive the abutting end of the intersecting mullion which reinforces the mullion thus out.

Another object of my invention is to provide a sash construction. in. which the mullions can be cut to form; the joints by. a dado saw, whereby in a multiple pane sash the tongues of the mullions are: formed by a. multiple dado saw which reduces the cost of:

constructing the sash and provides a joint for the mullions which increases the strength of the sash.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the 4 appended claims.

In the drawings,

Figure 1 is a front view of a four-pane sash constructed in accordance with my invention;

Fig. 2 is a rear view of the same showing the manner of securing the ends of the mullions in the stiles and rails in the manner of forming a joint at the intersection of the mullions;

Fig. 3 is a detail enlarged sectional view showing'the manner of forming the joint at the intersection of the mullions; and

Fig. 4 is a perspective detail view showing the end of one of the mullions in position within the notch of the intersecting mullions in dotted lines and the other mullion in full lines in position to be inserted.

Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing 1 and 2 indicate the stiles, and 3'- and 4: the rails of my improved construction of sash which has the appearance of an ordinary sash now in use at the front, and it is, only slightly changed at the rear as will be hereinafter fully described.

Arranged within the stiles and, rails of the sash are horizontally disposed mullions 5 and 6, and a vertically disposed mullion 7, the ends thereof being cut on. the ordinary machine in order to form extensions. 8 which are seated in notches 9 formed inthe stiles and rails of the sash as clearly shown in Fig. 2.

In constructing the joint at the; intersection at the horizontally and vertically dirposed mullions, the vertically disposed mullion-. which is provided with. the usual tongue formed by, the-rabbet is cut preferably by a dado saw and notched at 10 to receive the projecting. end portions 11 of the tongues 12 of the mullions 5 and 6 inorder to form a joint at the intersection of the mullions without weakening the. thickest portion of. the mullion, and itwill; be seen that when the mullions areseou-red together as shown, the joint thus formed; does not weaken the mullions in any way as the notch formed in; the tongue of, the, vertical mullion isv reinforced by the abutting ends of the extensions of the tongues of the intersecting mullions.

The ends of the abutting portions of the mullions are out in the usual machine so as to conform to the molded faces of the mullions, stiles and rails of the sash, whereby a sash is constructed having an ordinary appearance of a sash now in general use with the sash pane receiving shoulders in Which the lights can be inserted and secured in the ordinary manner, which lights also strengthen the joint thus formed so as to make it impossible for the mullions to separate from one another or from the stiles and rails of the sash.

Window sashes as heretofore constructed had the body portions of the mullions mortised to receive the tenon of the intersecting mullion which reduced the strength of the mullion to such an extent that in time the mullion gave away, while by my construction the weakest portion of the mullion is only notched which is reinforced by the abutting ends of the intersecting mullion toform a joint which does not decrease the strength of the mullion in any way.

dado saw which saws are mounted on a raduated shaft for adjustment so as to cut t e notches at the proper distance apart in the tongues of the mullions,- and as the ends of the mullion can be cut on an ordinary milling machine, it is only necessary to em ploy a router bit for forming the notches in the rails and stiles of the sash, and in some instances a dado saw could be employed for this purpose, and I do not wish tolimit myself in any particular way of forming the moldings, as the main object to be accomplished is the construction of a sash in which the mullions are secured therein in such a manner that the joint formed at the intersection of the mullions is such that the mulin any Way.

' 1 Wardly projecting tongues extending into abutting Within said notch.

2. A window sash comprising side stiles the notchfof the first-mentioned mullion and and top and bottom rails, a vertical mullion having its ends secured Within the t0 and bottom rails of said sash and provide with a notch horizontally disposed, mullions having their ends seated in the side stiles and provided with outwardly projecting end portions extending into and abutting within the notch of the vertical mullion.

3. As a new article of manufacture, a windoW sash comprising side stiles and top and bottom rails, mullions carried by said stiles and top and bottom rails provided with longitudinally disposed tongues, the tongue of one of said mullions being notched to receive the outwardly projecting tongue portions of the intersecting mullions, said tongue portions abutting within the notch of the first mentioned mullion. 1

4. A Window sash comprising stiles and rails and intersecting mullions, said mullions having longitudinally disposed tongues, one mullion having its tongue notched at the intersection of said mullions, the body of the intersecting mullions being cut away and shaped to conform with the shape of the body ofthe other mullion, the tongues-of said intersecting .mullions extending into and abutting within the notch of the first mentioned mullion.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
